I have tried to get the wireless network to accept the WAP security code. I go to network and then editing wirelss connections > Wireless security> WAP personal and then install the security numbers and letters. 'SAVE' doesn't come up it is greyed out? Hope you can assist

Just to get a better understanding I'm going to ask a few other questions. I am assuming you have WPA security set up on your router correct? And is wireless showing up at all? I know when doing a fresh install of linux the wireless does not work right away. After a fresh install I normally hard wire via ethernet then run "sudo apt-get update" from terminal and it will pull down the wireless drivers necessary for my device. If you can see the wireless there already and just can't access it because you can not enter the security code then let me know I will try to recreate the issue and see if I can find a fix

First let me appolagise as I live on 300mg morphine a day so get confused easily. I have hard wired internet to my router. When I set up the router it did not ask me to input my security I just went straight in. When I found the security area I tried to input the long code and it would not allow me to do so. My Windows OS and my wireless HP printer use the WAP and security code. This Linux Mint hasn't allowed me to set it up. Or, it might be simply I have gone into the wrong sofware and done it all wrong. If so where do I go to input the WAP and install the security to the router?

It is either WEP or WPA wireless security, not WAP ??--and if windows OS sees it, you have the code there on the windows OS network setups, you should be able to copy it to a removable device, eg a USB drive and then reuse that code under Linux OS (copy & paste function)

You possibly need a gksudo to prefix the network manager application when starting the network, if you are not using the admin (earlier Mint versions) or sudo group (later mint versions) account to setup that wireless client--if you are, then the save option if the data entries you used are correct will save the file for you..https://help.ubuntu.com/community/RootSudo

Thanks for all the info. Shall have to get my morphined brain to slowly dissect it all. I have a D-Link 2740R and I did get the wpa and wap mixed up as usual. Thanks for all the info. I had copied and pasted the security but it hadn't accepted the code. So I shall have to TRY and slowly digest all this reading (which I am not good at digesting info) and make sense of it all

I am thinking none of this is giving me the answer I am looking for. I should not have been able to link Linux Mint straight into my router without the security code!? So I have no idea how it connected. However its wired in with a ethernet cable and I am looking how to ensure the security code is used with WPA. As stated before my printer and Windows7 are secure with WPA. I shall keep looking but I do get easily confused
